RESUMEN
AIM: To evaluate the efficacy of oral sucrose combined with non-nutritive sucking for reducing pain associated with retinopathy of prematurity screening. METHODS: This was a randomised controlled study of 64 infants undergoing eye examination for retinopathy of prematurity screening. Topical anaesthetic (Proparacaine; Alcaine(®) drop 0.5%: ALCON CANADA Inc., Mississauga, Canada) was applied 30 sec before the eye examination in all infants. The infants in intervention group (Group 1, n = 32) received 0.5 mL/kg of 24% sucrose with a pacifier. The control group (Group 2, n = 32) received 0.5 mL/kg of sterile water with a pacifier. RESULTS: The groups had similar gestational ages (28.5 ± 2.8 weeks), mean birthweight (1304 ± 466 g) or corrected gestational age (35.4 ± 3.7 weeks) at examination. The intervention group had a significantly lower mean Premature Infant Pain Profile score during examination of the first eye, following insertion of the speculum (Group 1:13.7 ± 2.1 vs. Group 2:16.4 ± 1.8, p = 0.001). CONCLUSION: Although sucrose combined with non-nutritive sucking modestly reduces pain scores during eye examinations, there is need to further studies to explore significant pain relief for infants undergoing retinopathy of prematurity screening.
